loglike(endog, mu, freq_weights=1, scale=1.0)¶
The log-likelihood function in terms of the fitted mean response.
endog : array-like
Endogenous response variable
mu : array-like
Fitted mean response variable
freq_weights : array-like
1d array of frequency weights. The default is 1.
scale : float, optional
Not used for the Binomial GLM.
llf : float
The value of the loglikelihood function evaluated at (endog,mu,freq_weights,scale) as defined below.
If the endogenous variable is binary:
If the endogenous variable is binomial:
where with and as defined in Binomial initialize. This simply makes the original number of successes.
